11 Claims.

This invention relates to improvements in machines for use in applyingpressure to shoe bottoms and is illustrated herein as embodied in anapparatus adapted more particularly for use in cement attaching soles toshoes.

thereafter secured to the shoe bottom by nails after which the heel orthe heel base is attached to the heel seat portion of the sole byadditional nails. In attaching the heel end of the sole to theshoe bynails the edge portion of the sole is forced tightly against the heelportion of the shoe bottom and, since the nails are clinched on theinside of the shoe, this edge portion is maintained permanently in suchposition. The heel attaching nails likewise cause the edge of the heelor heel base to be forced into close fitting relation with the edge ofthe sole and they hold these edges permanently in that position so that,after the sole has dried out, no openings or spaces will appear betweenthese edges such as might result if no nails were used owing todifferences in the firmness of the leather materials at the heel seatportion of the shoe which cause the leather to react more in some placesthan in others and tend to return to its original uncompressed conditionwhen the heel attachingpressure is relieved.

When, however, the heel portion of the sole is to be attached to theshoe bottom by cement alone and when, in addition, as is the case with"many shoes manufactured today, the heel or heel base is also to beattached to the heel seat portion of the sole by cement alone, a problemarises with respect to securing and maintaining a close fittingrelation'between the edges of these parts 40 at the heel end of the shoebecause, in such cases,

no nails will be present to maintain said edges permanentiy in the closefitting contact they had while under heel-attaching pressure.

Accordingly, unless some means is provided for overcoming thesedifficulties, shoes having both the heel seat portions of their outsolesand their heels or heel bases attached by cement alone to produce aso-called nailless heel seat are apt to have spaces or openings appearbetween the sole edge and the shoe bottom at the heel portion of theshoe, or between the sole edge and the edge of'the heel or heel base.

Objects of the present invention are to provide improved apparatus foruse in applying pressure to soles and shoes including the entire heelportions thereof, and to provide improved means for operating on theheel seat portions of soles during the application of pressure theretoin order to eliminate the difi'iculties above referred to inconstructions in which both the heel seat portion of the sole and theheel or heel base are to be attached respectively to the shoe and thesole by cement alone.

To the attainment of these objects and in accordance with one of itsfeatures, the invention provides an improved pad box structureconstructed and arranged to apply pressure to the entire areas of a soleand a shoe bottom and simultaneously to mold or conform the heel portionof the sole to the shape of the attaching face of a heel or heel base.As illustrated herein, the pad box has a yieldable pad provided with asole and shoe receiving surface which is deformableunder pressure and isarranged to extend over the entire bottom area of the largest shoe tobeoperated upon. A smooth surface for engaging the sole is provided by acontinuous flexible blanket or cover, preferably of resilient material,which can be deformed with the yieldable surface of the pad during thepressure applying operation.

The improved means referred to for operating on the heel portion of thesole comprises, as herein illustrated, a rigid plate interposed betweenthe yieldable pad and the flexible cover and constructed and arranged tomold or conform the heel seat portion of the sole to the shape of theattaching face of a heel or heel base while sole attaching pressure isbeing applied to the sole and shoe, thereby producing a smooth, evencompressed edge on the heel seat portion of the sole which could not beobtained by pressure from a yieldable pad alone owing to hard and softspots in the material of the sole. As illustrated, the rigid plate has afloating contact with the operating surface of the pad so that it isfree to tip or bemoved heightwise of the shoe with said surface as thepad and cover are deformed under the pressure applied to the shoe andsole. The operating surface of the plate is concave and corresponds inshape to the attaching face of a heel or heel base so that, as thepressure isapplied, the heelseat portion of the sole will be molded orconformed to the shape of said attaching face. This insures that theedge of the sole will be compressed evenly and without high and lowplaces which would cause open spaces'between the sole edge and shoe orbetween the sole edge and the edge of the heel or heel base after theheel attaching pressure was relieved in cases where cement alone wasused to attach the sole to the shoe bottom and. to attach the heel orheel base to the sole.

In accordance with another feature of the invention, the conformingplate is adjustable longitudinally of the pad box, thereby permittingthe plate to be readily positioned for operating on soles of differentlengths. As illustrated herein, the adjustment of the plate is effectedby manually operated means whereby the plate may be moved predetermineddistances lengthwise of the pad without interfering with its freelymovable floating relation to the pad or the pad cover. Moreover, thelongitudinal adjustment may be accomplished, in accordance with thepresent invention, without displacing the flexible pad cover overlappingthe plate or interfering with the operation of the pad or mechanismsassociated therewith.

Still another feature of the invention comprises an improved arrangementfor insuring that the heel end of the sole will always be properlypositioned on the pad relatively to the shoe. Since the flexible coveroverlaps the concave surface of the rigid heel conforming plate, thecover may, under continual use, gradually conform to the concave shapeof said surface and thus render it difiicult for heel positioning gageswhich are arranged to operate in a fixed or predetermined plane toengage the edge face of a sole located in this concave or cuppedsurface. This difficulty is overcome in the present construction bycausing the operative ends of positioning gages for locating the heelend of the sole relatively to the shoe to rest by their own weight orgravity on the surface of the pad cover and to ride or slide on thissurface during their operative movement into engagement with the sole.In this way there is no opportunity for the gages to ride over the topof a sole located in a concave depression at the heel end of the pad andconsequently danger of the gages failing to engage and position the soleis eliminated.

With the above and other objects and features in view, the inventionwill now be described in connection with the accompanying drawings andwill thereafter be pointed out in the claims.

The invention is illustrated herein as embodied in a pad box for use ina cement sole attaching machine of the type disclosed in Letters Patentof the United States No. 2,047,185, granted July 14, 1936, on anapplication filed in the name of Milton H. Ballard et al., this pad boxbeing modified in the manner disclosed in Letters Patent of the UnitedStates No. 2,005,755, granted June 25, 1935, on an application filed inthe name of Francis J. Better, to adapt it more particularly foroperating on large size shoes, such as mens shoes. As disclosed in theBallard et al. patent, the pad box is secured by screws 12 to a radiallyprojecting portion l3 of a supporting shelf or table which forms aportion of a rotary turret on the cement sole attaching machine. The padbox comprises a fixed casting M for supporting the rear portion of ayieldable pad l6 and a movable casting [8 arranged to swing about acenter 20 for supporting the forward portion of the pad and forpositioning this portion at a. proper angle for the shape of the shoebeing operated upon. As herein illustrated, the yieldable pad I6comprises a hollow bladder, preferably of rubber, filled with fluid suchas Water, and it extends to the rear or right-hand end of the fixedcasting 14 of the pad box, as shown in Fig. 8. The movable casting l8carries sole and shoe positioning gages, indicated generally by thenumeral 22 and being of substantially the same construction as thosedisclosed in United States Letters Patent No. 2,063,041, grantedDecember 8, 1936, on an application filed in the name of Lloyd G.Knowles.

The rear or right-hand end of the pad box as viewed in Fig. 1, isprovided at its opposite sides with vertical guideways 24 in which isadjustably mounted a slide member 26 the upper end of which projectshorizontally to form a supporting plate or table 28 upon which ismounted gage mechanism for relatively locating the heel ends of a soleand shoe on the pad, the plate 28 also supporting mechanism forming apart of the present invention for conforming the heel portion of a soleto the shape of the attaching face of a heel or heel base during the'application of pressure to the sole and shoe. The slide 26 is adjustedin the guideways 24 and is main tained in adjusted position by a screw30 (Figs. 3 and 8) threaded into a horizontally projecting lug 32 formedon the lower end of the slide, the screw being secured by a lock nut 34in a fixed bracket 36 fastened by screws 38 to the casting [4 of the padbox. In adjusting the slide 26 heightwise of the pad box the lock nut 34is loosened and the screw 30 is turned until the proper heightwiseposition of the slide is attained, after which the lock nut is made fastagain against the fixed bracket 36. The heightwise position of the slide26 is determined, in a manner to be hereinafter explained, in accordancewith the amount that the flexible pad I6 is distorted under the soleattaching pressure. It will be seen from the above that the slide 26 andthe mechanism carried thereby are fixed against movement heightwise ofthe shoe during the operation of the machine but that they are capableof adjustment heightwise of the shoe.

The horizontal projection 28 on the slide 26 carries sole and shoepositioning mechanism with which a pad box of the present type isprovided for relatively positioning the heel ends of a sole and shoe onthe pad, this mechanism comprising, as fully disclosed in the, Betterpatent referred to, a plurality of substantially horizontal members 40(Figs. 1, 3 and 8) which carry a pair of transverse slides 42, 44adapted to operate, respectively, by means of inclined slot and rollarrangements 46 (Fig. 6) and 41 (Fig. 4) a pair of pivoted shoepositioning gages 48 and a pair of pivoted sole positioning gages,indicated generally by the numeral 50. The gages of each pair areinterconnected respectively by gear segments 52, 53 for equal andopposite swinging movement toward and away from a shoe and sole on thepad. The transverse slide 44, which operates the sole positioning gages50, is caused to move inwardly of the machine away from the operator bya tension spring 54 (Fig. 8) when a roll 60 (Fig. 6) is removed fromengagement with the end of the slide by treadle operated mechanismincluding a bell crank lever 62 operating the roll 60 through a link 64,this lever 62 being also arranged to operate the forepart gage mechanism22 through a second link 66 which connects it to said mechanism.

The transverse slide 42 for operating the shoe heel gages 48 is actuatedthrough the movement of a swinging frame member 68 (Figs. 1 and 3) whichis arranged to be moved manually from, a rearwardly inclined,inoperative position into a substantially vertical, operative positionby a handle if The slide 42 is connected by a rod I2 to a pivoted arm M(Fig. 3) on the swinging frame 68 so that forward movement of theswinging frame causes the slide 42 to be moved forwardly toward theoperator and, by reason of the roll and inclined slot arrangementpreviously referred to, to move the inter-connected shoe gages 48 intoengagement with the shoe resting on the sole.

As shown in Figs. 1 and 8, the several gage supporting members 49 arearranged for pivotal movement about a horizontal pin I6 so that theoperative ends of the gages may yield upwardly, if necessary, during thepressure app-lying operation, the normal position of the gages, however,being determined by a stop screw I8 (Fig. 1) and a compression springwhich constantly urges the lower member of the group 40 against the stopscrew. The gage mechanism may also be adjusted longitudinally of the padbox by means of a slot 82 (Figs. 2 and 8) formed in the supporting plate28, the mechanism being secured in adjusted position, however, duringthe operation of the machine by a thumb screw 84 passing through theslot 82 and threaded into a spacing block 85 and a slide 88 mountedthereon, these last-mentioned members supporting the members 48 and gagemechanisms carried thereby and locating the gage mechanisms in a properposition heightwise of the pad box for operating on the heel ends ofmens shoes.

The supporting plate 28 of the slide 26 has secured to its left-handportion, as viewed in Figs. 1 and 8, a plate 98 which is shaped like theheel end of a large shoe in plan view and-has an upstanding wall 94adjacent to its edge which forms a heel shaped container for supportinga yieldable heel engaging pad 86, preferably formed of solid butrelatively resilient material such as rubber. The pad 96 is shaped atits left-hand end (Fig. 8) to join with the adjacent wall of the fluidfilled pad I6 which underlies the forepart and shank portions of theshoe and sole and, as shown in Figs. 8 and 10, the pad 96 extends abovethe wall 94 so that its exposed surface coincides substantially with theyieldable surface of the pad I6 when both pads are under pressure, thisheightwise position of the pad 96 being determined by the positionoftheslide 25 g which, as previously pointed out, is controlled by theadjusting screw 36. Overlying the top or sole and shoe supportingsurfaces of the adjoining pads I6 and 96 is a flexible blanket or cover98, preferably formed of resilient material such as rubber and forming acontinuous unbroken surface for receiving the sole which is to beattached to the shoe bottom.

Extending downwardly from each side of the plate 99 is an ear I00 and inthese ears is r0- tatably mounted. a transverse shaft I02 having securedto its opposite ends by pins IE4 (Figs. 1 and it!) a pair of upwardlyextending arms Hi8. The upper ends of the arms IE6 have pivotallyconnected thereto, by pins 598, a pair of substantially horizontal linksHi3 which, at their other ends are pivotally connected by pins I I2 to asubstantially heel shaped plate I I4 which is fiat on its lower surface(Fig. 8) and is cut away or cupped at its upper or operating surface IIB(as shown in Figs. 5, 8 and 10) to correspond substantially in shape tothe concave surface of the attaching face of a heel or a heel base ofthe proper size and shape for the shoe on the pad. The plate H4 ispreferably composed of metal such for example, as bronze and is rigidand non-yielding under pressure. The arrangement of the arms I 06 andlinks III] is such that the rigid heel conforming plate is superposed onthe pads I6 and 96 and can ride or float on the upper surfaces of thepads, as best illustrated in Fig. 8, so that when these surfaces aredeformed under the sole attaching pressure applied by the machine, therigid plate will be depressed heightwise of the shoe but will bereturned to its initial position by the pads when the pressure on theshoe is relieved. The rigid plate H4, as shown in Figs. 5 and 8, isarranged to be interposed between the yielding surfaces of the pads I6and 96 and the continuous flexible cover 98 and may be located in suchposition lengthwise of the pad box that it will operate to conform ormold the heel seat portion of the sole to the shape of the attachingface of a heel while the sole and shoe are being pressed together duringthe pressure applying operation, the sole at this time being insuficient temper to permit its conformation under pressure. Since theflexible cover 98 rests on the concave surface of the conforming plateII4 it may and usually does under continual use partake of or conform tothe shape of this surface so that it ultimately becomes concave in shapeeven when no pressure is being applied to the sole and shoe.

It is desirable that the rigid sole conforming plate H4 be adjustablelongitudinally of the pad toposition it for operating on soles ofdifferent lengths. To this end the arm I 96 at the front side of thepad, as viewed in Fig. l, is provided with a forwardly projecting studIIS (Figs. 1 and 7) rotatable in the arm and having an ear I23 (Fig. 10)in which is mounted a pin I22. Pivoted to this pin is a substantiallyhorizontal link I24 pivotally connected at its other end by a pin 52% toan ear I28 rotatably mounted on an arm I39, which, in turn, is pivotedby a vertical pin I3! to a forwardly projecting plate I32 secured byscrews I36 to the under side of the slide block 86. As shown in Figs. 3and 10, the vertical ,pin I3I extends through the plate 532 and is heldtherein by a cotter pin, and a compression spring I 36 is mountedbetween a head on the pin l3I and the arm I30 to hold the latternormally against the plate I32. Forwardly of the projection I28 the armI30 carries a downwardly extending indexing pin I38 (Fig. 10) which isarranged to enter any one of a series of holes I 49 formed in the outerportion of the plate I32 on a radius struck from the center I3I and thusto adjust the plate I I4 into proper positions longitudinally of the padfor operating on soles of different lengths. The arm I30 forms a handlewhereby the upstanding arms I96 may be swung as a unit with their shaftN32 to adjust the heel conforming plate II4 forwardly and rearwardly ofthe pad box between the cover 98 and the upper surfaces of the adjoiningpads I6 and 28. The pin l38 may be withdrawn from one of the holes I46and inserted in another by moving the handle I30 manually against thecompression spring 536.

The conforming plate II4 is provided at the opposite sides of itsleft-hand portion, as viewed in Figs. 1 and 10, with upwardly projectinglugs I42 having upper portions extending inwardly toward each other.These projections overlie the upper surface of the pad cover 98 justforwardly of, or toward the toe end of the pad relatively to, a pair ofrectangular projections I44 (Figs. 6 and 9) formed on the opposite edgefaces of the cover 98. The cover is thus maintained in substantialcontact with the operating surface IIE of the sole conforming plate I Mby the overhanging lugs 42 and it is also prevented by the projectionsI44 from buckling or becoming loose longitudinally of the pad during theapplication of sole attaching pressure to successive soles and shoes.

As indicated above, the flexible cover 98 may tend under continual useto conform or shape itself to the concave operating surface of the rigidplate H4 so that the upper surface of the cover upon which thesole restsis likewise concave. The sole gages 50 and shoe gages 48 are carried bymechanism which, while it is capable of adjustment angularly withrespect to the pad by reason of the pivot '56, spring 85 and adjustingscrew I8 (Fig. l), is not, as disclosed in the Better patent mentionedabove, normally arranged to permit the sole gages to rest by gravity onthe pad or to ride on the surface thereof during their operativemovement toward or away from the opposite edge faces of the sole.Accordingly, in order to insure that the sole gages 50 will rest bygravity on the exposed surface of the flexible cover 98 and will ridealong this surface during their operative movement, the sole gages havebeen constructed in the manner illustrated in Fig. 9 to permit theoperating portions of the gages to ride on the surface of the pad cover98 and thus to be always in a position to engage the opposite edge facesof the sole. As shown in Fig. 9, the interconnected segmental portions53 of the sole gages rest on, and are actuated by the trans verse slide44. These portions 53 are provided with laterally extending arms 548which are bifurcated to form ears at their left-hand ends and havepivotally secured thereto, by pins I55, extensions or arms I52, theleft-hand ends of which form the sole heel gages proper. This pivoted orhinged construction of each gage arm I48, I52 permits the operative endsof the sole gages torest by gravity on the surface of the pad cover 98and thus causes them to ride over this surface during their operativemovement toward and away from the opposite edge faces of the sole.Accordingly, the gages will always engage and position the soleirrespective of its thickness and irrespective of the shape of thesurface upon which the sole rests.

The cement sole attaching machine in which the pad box of the presentinvention is embodied is provided with abutments I54, i56 (Fig. 1) forengaging, respectively, the forepart of the shoe and the last in theshoe. These abutments are operated, as disclosed in the Ballard et al.patent, by substantially .horizontal pressure applying levers I58 (Figs.1 and 3) to apply the sole attaching pressure to the sole and shoe.

Although the operation of the mechanism embodying the present inventionwill be apparent from the foregoing description, a brief summary will begiven for the purpose of clearness. The operator places a sole A on thepad cover 98 and depresses a gage operating treadle on the cement soleattaching machine to cause the combined forepart sole and shoe gages 22and the heel end sole gages I52 to move into engagement with theopposite edge faces of the sole, the forepart gages merely finding thesole on the pad and becoming locked in operative position while theequally and oppositely movable heel sole gages move the heel end of thesole bodily relatively to the pad to locate it thereon. As stated above,the sole gages I52 ride on the concave or cupped surface of the padcover 98 during their sole positioning movement. After positioning theheel end of the sole on the pad, the sole gages I52 become lockedagainst movement away from the sole by reason of the roll and inclinedslot arrangement 47 on the slide 44, as fully described in the Betterpatent referred to above. Since the sole A is thus located on the padand is positively positioned longitudinally thereof, the operator cansee where the heel seat portion of the sole is located with respect tothe sole conforming plate H4. Consequently, he can, if necessary, adjustthis plate lengthwise of the pad by the handle I36 until the plate is ina position to operate only upon the heel seat portion of a sole of thesize mounted on the pad. During this adjustment the sole conformingplate slides readily between the pads IIS and 96 and the pad cover 98,and the pad cover is prevented from being displaced relatively to thesole conforming plate.

by the overhanging abutments I42.

The operator places a shoe B, assembled on a last C, on the sole, theforepart of the shoe being positioned relatively to the sole by thelocked forepart gages 22. It will be understood, of course, that theinner or attaching surface of the sole, including its heel end, and themarginal portions of the entire shoe bottom have been previously treatedwith a suitable cement such, for example, as pyroxylin, and that thiscement has been activated and is otherwise in condition to attach thesole permanently to the shoe bottom when pressure is applied to the soleand shoe.

The operator next swings the swinging frame member 68 forwardly into asubstantially vertical position, as shown in Fig. 3, by the handle I0,thereby locating the shoe engaging abutments I54, I56 in position toengage respectively the forepart of the shoe and the top of the heelportion of the last 0. He now depresses a pressure applying treadle onthe machine to actuate the fluid pressure operated pressure applyingmechanism thereon and to cause the levers I58 to move the abutments I54,I56 into engagement with the shoe and last and thereby to apply the soleattaching pressure. This action sinks the sole and shoe into the padcover 98 and into the yieldable surfaces of the pads I6 and 96, therebydeforming these surfaces and depressing them heightwise of the shoe.Since the shoe conforming plate H4 is connected by the pivoted links H!)to the adjusting arms I06, the plate is, of course, free to moveheightwise of the shoe as the pad cover 98 and the surfaces of the padsare deformed and depressed. Consequently, when the full pressure hasbeen applied to the shoe and sole, the rigid conforming plate H4 moldsor conforms the heel seat portion of the sole A to the shape of theattaching face of the heel which is to be attached to the shoe, themolding taking place while the heel seat portion of the sole is beingpermanently attached to the shoe bottom by cement. At the same time, theportions of the sole A forwardly of the heel portion are being cementattached to the shoe bottom under the pressure exerted against the soleby the forepart and shank portions of the pad. When the pres sure on theshoe and sole is relieved as the pad is about to return to the operatingstation, in the manner described in the Ballard et al. patent, the soleA including its heel seat portion will be permanently attached'to theshoe bottom and this heel seat portion will also be molded or conformedby the rigid plate I I4 so that it is substantially complemental totheattaching face of a heel or a heel base.

It will be seen from the foregoing that the present invention not onlyprovides for the permanent attachment of the heel portion of a sole to ashoe bottom in such a manner that the edge portion of the sole islocated in close fitting relation with the shoe bottom, but it alsoprovides for simultaneously molding or conforming the heel seat portionof the sole to the shape of the attaching face of a heel or heel base sothat the latter may be applied to the sole by cement alone withouthaving openings or spaces appear between the edges of the sole and theheel or heel base caused by an irregular or wavy edge on the heelportion of the sole. Since the sole conforming mechanism is adjustablefor various sizes of shoes without disturbing either the pads or thesole and shoe positioning mechanism, the-apparatus is easy to operate.The convenience with which the heel conforming plate may be adjustedlengthwise of the pad and the accuracy with which this adjustment may beeffected owing to the fact that the operator can see the longitudinalposition of the sole on the pad before he makes the adjustment, all tendto render the use of the apparatus quick, economical and eflicient.
